"Dr. Keskin is the best doctor I've ever had. I suffered from unbearable pain for 3 years due to bruxism. I visited jaw specialists at the USZ and countless physical therapists, but for 3 years nothing helped. I went to his practice because I started having chest pains on the left side. He examined everything and was the only doctor who could tell me why it was like that and what I should change. Now, 5 days later, I am so grateful to him because after 3 years of daily pain, I simply have no more.!!!"
"I am really glad to have found this practice. Dr. Keskin is a sensitive and intelligent doctor. He supported me both psychologically and medically during many examinations. I can only highly recommend him."
"Excellent doctor – attentive, friendly and committed. I am really glad I found this doctor. From the start he's been there for me—totally attentive and honestly interested in my overall health. He took the time to carefully examine my situation, and I never felt like he was overlooking anything. When anything was unclear, he explained it patiently and showed me all the steps of the treatment. What I particularly like is his aftercare. After the treatment, he kept getting in touch, checked my healing progress and was available for questions. These regular follow-ups give me the good feeling that someone is truly interested in my sustainable recovery. Professional and fachlich top. His friendliness is clearly noticeable—not intrusive, but gentle and reassuring. Overall a truly positive experience."

"Possibly one of the best decisions of my life! After many years with my old GP, I switched to Dr. Keskin. Dr. Keskin describes current problems with an extremely pleasant tone and in a way that is understandable for every patient. In these past three years, he has scored a bullseye with my diagnoses every time and kept me from a superfluous biopsy, as well as detecting the narrowing of my heart veins efficiently. My family and I are very grateful to him for his excellent work as a doctor and his friendly nature."
"Dr. Kirsken, through his persistence in searching for the cause of heart flutter, saved my wife from a heart attack and me from being a widower. We are very grateful to him and his competent team. We can only recommend the cardiology practice. Wolfgang Müller"
"I am being treated by Dr. Keskin and am very satisfied. He always takes his time, explains everything clearly and treats very competently. Friendly and well organized. Clear recommendation!"
"Hello, my name is Anastasie Alexandru and I am 30 years old. I live in Germany and I want to tell you that 5 years ago I noticed that I had very high blood pressure over 200/110, even though I didn't feel anything. One day I went to Mr. Sergej Kauz for a sore throat, and he described Dr. Keskin to me. I made an appointment; everyone there spoke nicely and behaved exemplary. I was examined immediately, and to my surprise, he prescribed new medication and my blood pressure started to normalize. Special thanks to Mr. Keskin and everyone who works there. You do an excellent job."
"My name is Sergej Kauz, I am 50 years old and work as a chiropractor in Germany. Since I was 35, I have struggled with high blood pressure (over 200/110) and ignored it for a long time. Last year my father died early from cardiovascular problems, which scared me. I went to Dr. Keskin on a recommendation—and that was the best decision. He examined me thoroughly, took 40 minutes and explained everything patiently using the monitor. The biggest surprise came the following week: Dr. Keskin prescribed a minimal dose of medication that finally regulated my blood pressure! For seven months now, my blood pressure has been constant at +/-120/80. I am very grateful to Dr. Keskin for his competent and empathetic treatment."
